No flames here, but you can also buy the Winchester 147 gr JHP at Wallyworld for about $15.00 for 50 rds.

Lots of practice rounds is a good idea. Burning a couple of mags of what you will load for self defense as the last of the day is an even better idea. Finish off your practice with what you will load for defense, in whatever caliber. If you load 147 gr 9mm as your defensive rounds, knowing what that round does to your sight picture following each shot is important to competency.
